Former two-time Bellator lightweight champion Eddie Alvarez has inked an exclusive deal with the UFC, and is now scheduled to make his long-awaited promotional debut against Donald Cerrone at UFC 178. That bout will serve as the co-main event of the September 27th pay-per-view.

UFC officials announced the signing on Tuesday, less than 12 hours after new Bellator president Scott Coker granted Alvarez his unconditional release from his Bellator contract.

Alvarez (25-3) enters having defeated 10 of his previous 11 opponents, eight of which he ended via stoppage. The 30-year-old is widely considered to be one of the top lightweight fighters in the world, and most recently avenged his loss to Michael Chandler by capturing a narrow split decision victory over the former Bellator champion last November.

Cerrone's initial opponent, Bobby Green, is expected to receive a new match-up at a yet-to-be-determined date.
